can't change site URL

I have tried the three methods (functions.php, wp-config.php, and phpAdmin) described in the article below multiple times (minus the relocate method) to change the WP siteURL. None of these methods have worked for me.

Any error message?

For editing the wp-confi.php depending on things I did, I got different errors depending how I did it.

If I add the lines immediately the “happy blogging” comment, I get timed out errors from my blog and admin log in page.

If I add the lines before the define(WP_SITEURL’, $pageURL) part, my blog is visible only as html. But I can’t log back in because of ‘timed out error’.

If I add the lines at the very end then no error message, and instead of one being greyed out, both are. While it will change the “Site Address URL” it will not change the “WordPress Address URL”

For editing the functions.php, I don’t get errors. The process will change the “Site Address URL” without greying it out, but it won’t change the “WordPress Address URL”. (I check in admin before deleting the lines I added).

If I add the lines immediately the “happy blogging” comment

What “lines” are you trying add?

The only text I added to the wp-cofig.php file was
define(‘WP_HOME’,’https://blog.tetibellecrafts.com/wordpress’);
define(‘WP_SITEURL’,’https://blog.tetibellecrafts.com/wordpress’);

Example when I add this text at end of file.

For the functions.php file it was
update_option( stieurl’, ‘https://blog.tetibellecrafts.com/wordpress’ );
update_option( ‘home’, ‘https://blog.tetibellecrafts.com’ );

sorry, typo in previous post. thanks.
update_option( ‘siteurl’, ‘https://blog.tetibellecrafts.com/wordpress’);

I have similar problem. Any idea?
